Good touch screen stereo navigation system for grand marquis?

sonicelectronix.com/item_1714… only requires 4 screws to hold it in so its not that hard to remove an put in a vehicle within 10mins unless your just lazy. Its not a waste, this has hands free bluetooth,navigation,plays dvd's, sd card slot,usb, music video,view pics,has I pod jack, plenty of outputs, a spot for the back up camera to plug in(all you need is the camera itself). All for $199..... the $199 has a 7" screen compared to a 3 inch screen on a gps.

Here are some that are a bit cheaper sonicelectronix.com/viewcat.p….

Built in navigation systems are a waste of time and money. You can get a Garmin Nuvi or a TomTom for $100 or less and it will do everything you need, plus you can move it from one vehicle to the next with no tools.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
